es ees- To all whom may concern.-

Be 11; known that I, VILLIAM'H. BROOKS, a citizen of Great Britain, residing at San Jose, in the county of Santa Clara and State of California, have invented certain new and useful Improvelnentsin Attachments tor Dough-Mixers, of wlnch the following 15 a specification, reference being had to'the accompanying drawings.

Thisinvention relates to dough mixing machines, and particularly to an attachment therefor designed to support receptacle rom which the contents may hedischarged into a mixingibowl.

Oneobjcct of my invention is the provi: sion of an attachment of this character, which is adapted to be applied to'inachines for mixing bread dough or cake dough, and

designed to do away with the necessity of the material which is to be mixed with the.

batter being'manuall y poured into the mire ing bowl. A V 1 A further object of the invention'is to provide means whereby the passage of material into the mixing bowl may be controlled and regulated.

A further object is to provide areceptacle for containing material which is to "be mixed with the batter, provide a holder therefor which may be engaged with the dough niixing machine, and provide means for straining the natcrial as it is poured intosaid receptacle.

A further object is to provide a device of this character wlii c'h is soconstructed that all the parts may be disassembled. so as to the accom with tlrie cover and strainer removed and,

with the valve removed; 7

Referring to these drawings, 15 designates the standard or support of any ordinary dough mixing machine, which includes the bowl l6 and the beater 17, which is operatively mounted upon a rotatable shaft 18 the ournal driven by gearing from a motor, in theusual; manner. It is not believed necessary to de; scribe in detail the various parts of this Inachine, inasmuch as it is of a well known type;

and formsno part of my present invention. My invention relates to means for supporting a receptacle 1 upon a dough mixing machine, in such a position that the contents of I the receptacle will be discharged into the, bowl 163.

The receptacle 1 is open at its upperend, but at its lower end is provided with a plurality of perforations at. Preferably these perforations a are arranged in rowwthere being as many rows as possible of varying sizes to suitvarious fluids or mixtures. Removably disposed in the upper end of the receptacle is a. funnel 2 having atitslower end a strainer The upper end of the receptacle is closed by a cover 3. Below the perforations 5% of the receptacle is arranged a spent 5, which extends downward and which is so disposed as to discharge the ma-' terial passing through the holes 4: into the bowls l6.

ever make or style. it will be noted from,

Fig. 1 that the annular portion 13 is joined to the arms 13" by an intermediate web 13 and that this web is downwardly inclined from the arms 13 and that the annulus 13 is not disposed in a horizontal plane when the holder is in position on the machine, but is upwardly inclined so that the receptacle 1 when in place within the holder, is tilted so that its contents will gravitate toward the openings l.

For the purpose of controlling the outlet of material from the receptacle 1 through the openings 4. I provide a segmental valve 6, which upon its under side provided with a layer 7 of rubber or other soft material. This valve at one corner is provided with the downwardly extending stem 8, which is screw-threaded at its outer end, many sided and preferably square in cross section at its middle portion, and round at that portion which is disposed adjacent the valve. Connecting the screw-tlnrezuled portion of the stem a wing nut 9. Mounted upon the under face of the bottom of the receptacle 1 is a bearing collar 10 having a central hub and a radially extending stop 10 The stem 8 passes through this bearing so that the round portion of the stem operates within the bearing and connected to the square portion of the stem is a handle 11. This handle at one end is formed with a square openin to receive the squared portion of the stem 8 and with two stops diametrically disposed at this end of the handle and designated 11 which coact withthe stop 10 The free end of the handle is formed with an arcuate flange 11 having thereon graduations 12. Preferably on one end of the flange i's'theword Open and at the opposite end the Word Close. The body of thehandle is formed with a downwardly extending, medially disposed flange 11 which forms-the means. whereby the handle maybe gripped and shifted.

In the practical use of this invention, the material which is to be mixed with the halter in the bowl 16, is poured into the receptacle 1 and passes through the strainer 2. Then the valve 6 is opened to any desired degree, depending upon the rapidity with which it. is desired to discharge the contents of the receptacle. The valve may be fully opened, or only partly opened. The contents of the receptacle then pass downward grzulually through the perforations in the bottom and are discharged by means ofv .the spout 5 into the mixing bowl. It will be obvious that the contents of the receptacle may be. discharged very slowly through a relatively long period of time or discharged relatively quickly. The holder does away with the necessity of an operator standing beside the bowl 17 and discharging the receptacle. into the bowl and waiting there untilthe contents of the receptacle are fully discharged. This provides for a more complete mixing of the material. with the dough and of more uniform mixing.

lVhile I have illustrated aconstruction which I have found to be very effective in practice, it is obvious that many minor changes might be made, without departing from the spirit of the invention.

Having thus described my invention, what I claim is 1. An attachment for dough mixing machines including a receptacle having perforations in one portion of its bottom, the remainder of the bottom being imperforate, a spout disposed below the perforated portion of the bottom. a valve resting on the bottom and rotatable thereover and adapted to overlie all or a portion of the perforated portion of the bottom. said valve having a stem formed with a circular portion, a succeeding many sided portion and a succeeding screw--threaded portion, a bearing mounted on the bottom and throughwhich the circular portion of the stem'passes, said bea-ripghaving limiting stops formed upon it, ahandle having a many sided opening to receive the many sided portion of the stem, and 'a nutYe-ngaging the screw-threaded portion of thestem and holding the handle ,uponthe stem, said handle bearing against. .Stlldbfifllflflg and being limited in its movement by said stops. 4

2. An attachment for dough mixing machines including a receptacle having a head at its upper end whereby it may be engaged with aholder, the lower end of the receptacle having a plurality of perforations at one portion thereof, a valve disposed on the bottom of the receptacle and movable into position to wholly or partially overlie the perforated portion of the receptacle and having a valve stem passing through the bottom of the receptacle, a handle attached to said stem, the handle providing means whereby the valve may be opened to a greater or less degree and indicating the po sition of the valve, a hopper removably disposed in the upper portion-of the receptacle and resting upon the upper edge thereof and having a strainer, and a cover engaging over the hopper and the upper edge of the receptacle.

In testimony whereof I hereunto atlix my signature in the presence of two witnesses.
